Valence  electrons  are number  of the  electrons  in  the   outermost   shell of  an  atom
silicon  has  4   valence  electrons
oxygen  has  2  since  in SiO3^-2  they  are  3  this  make  valence   electrons  to  be   6
SiO3^-2  have   negative  charge of  two  thes  means  has   two  extra electrons hence   has  2  valence  electrons

When a pure substance melts does its particles get larger
ziro4ka [17]
I think so ( for solids ) because you know when you melt chocolate it turns into a liquid and liquids allways move around together and it can't get smaller either so, I think you are right.

The processes of gluconeogenesis and glycolysis are said to be reciprocally regulated.Reciprocal regulation means thata) molecul
yawa3891 [41]

Answer:

Explanation:

Gluconeogenesis and glycolysis are coordinated so that within a cell one pathway is relatively inactive while the other is highly active. If both sets of reactions were highly active at the same time, the net result would be the hydrolysis of four nucleotide triphosphates (two ATP plus two GTP) per reaction cycle. Both glycolysis and gluconeogenesis are highly exergonic under cellular conditions, and so there is no thermodynamic barrier to such simultaneous activity. However, the amounts and activities of the distinctive enzymes of each pathway are controlled so that both pathways are not highly active at the same time. The rate of glycolysis is also determined by the concentration of glucose, and the rate of gluconeogenesis by the concentrations of lactate and other precursors of glucose.

The interconversion of fructose 6-phosphate and fructose 1,6-bisphosphate is stringently controlled (Figure 16.30). As discussed in Section 16.2.1, AMP stimulates phosphofructokinase, whereas ATP and citrate inhibit it. Fructose 1,6-bisphosphatase, on the other hand, is inhibited by AMP and activated by citrate. A high level of AMP indicates that the energy charge is low and signals the need for ATP generation. Conversely, high levels of ATP and citrate indicate that the energy charge is high and that biosynthetic intermediates are abundant. Under these conditions, glycolysis is nearly switched off and gluconeogenesis is promoted.

Which term is used when sugar is dissolved in water?a: covalentb: homogeneousc: amphibigeneousd: heterogeneous
Liula [17]
Homogeneous because it completely dissolved so its now one. Heterogeneous would be when they don't dissolve and you see 2 separate substances like sand in water.

Name an atom that loses one electron when it reacts to another atom
Hitman42 [59]
Lithium, Sodium, Potassium; any of the Alkali Metals, which are farthest left on the periodic table. This is because they only have one electron in their outermost shell, so they would rather lose an electron rather than try to gain 7 to achieve that full outer shell.
